Appucati'niued april 1e, 1era. serial nb; isa-asn To all whom it may concern: p

Be it known that I, VILHELM Solennit- GLUTH, engineer, a subject of the Empero-r of Germany, residing at Schiedam, Netherlands, have invented certain new .and useful improvements in Bottle-Blowing Maclnnn ery; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference vbeing had to the accompanying drawings, and 'to letters or {igures of reference marked thereon, which form a part of this specification.

Tith the usual bottle blowing-"machines the bottles assume, together with the molds in which they are contained, at the end of the process an inclined position relative to the vertical` the necks of the bottles pointing upwardly. ln this position the `head which projects from the upper end of the mold, is caught by a Apressure member provided with layer of asbestos, after which the mold is opened. The pressure member having released the bottle-head, the bottle falls head foremost into a funnel witha cylindrical bottom-part, sothat the bottle is guided and arrives with its neck in the corresponding aperture of a periodically rotating table, the bottle-mouth :being smoothed in this position by means of Bunsen burners. This device has, however, some drawbacks in blowing bottles, theA cross section of which diminishes toward the bottom, as

' such bottles will not be sufciently guided in the rectilinear part ot the funnel to arrive with their necks exactly above the apertures in the rotary table, while even if the aperture in the table were a larger one and if the bottle, because of its usually short neck, were made to penetrate over a greater distance into the table aperture, its conical end would not be sufficiently supported by the latter.

The object of the present invention is a device which eliminates the aboveunentioned drawbacks in order to securely receive the bottle in the aperture of the rotary table and to support it in same so that in this position it may be exposed to the influence of the Bunsen burners.

The principle of the invention is, brieiiy mentioned, to tip the bottle during its travel from the mold to the rotary table so that it arrives with its bottom downward in the the rotary, table aperture. action of the guide members of the funnel 'apertura Tn order to realize this, -the bottle "falls, after leaving the mold, on an inclined `table over the surface ci which it glides down, arriving thus on a pivoted part off the vreceiving table. This pivoted member is depressed by the weight of the bottie', vthe latter falling consequently into an aperture 'of the rotary table. If this aperture has so large a diameter 'that the bottle enters it as far as its widest part, a special `guidance of the bottle is superfluous. In case however, the bottle `has to remain at a higher level above` the table, the :table-aper- 'ture must be smaller than the cross section of funnel, the insuiiiciently guided bottle runningthe risk of being broken by striking against the `table. This point is also taken into account in designing the device according to the invention, the bottom part of the funnel being executed with swinging linembers of such shape that. when closed, they exactly iit around the bottle. When the latter falls down, from the pivoted table into the funnel, its velocity is reduced, the bottle traveling on until it has arrived above The swinging can lbe realized a very simple manner by keeping them closed by means of balance weights which are light enough to allow the .gu-ide funnel of being opened by the bottle arriving with a rather high velocity.

` In the 4accompanying drawing Figure l represents a top view, Fig. 2 a side elevation ofa device according to the invention 'in a form of eXecu'tion applied to machines for blowing the well-known square bottles.

In the form here shown the apparatus comprises an inclined trough-like receiving table a onto the upper portion of which the bottles are successively dropped from the mold and on which they successively take a position with the neck end down. The inoline of the table is sufficient to cause the bottles to slide downward in the trough thereof, until they reach the tipping table h, which, in its normal position, forms a continuation of the bottom of the receiving table and is pivoted at b1 thereto. ,A stop or head b2 at thel end of the tipping table prevents the bottles overrunning the latter. As soon as a bottle takes up position on the tipping table 79, the weight of the heavy end of the bottle at the upper end of the tipping table overbalances the counterweight ethereof and swingsthe table downward. As soon as its downward inclination is suiicient, theV bottle, now with its neck end up, discharges into the vertical vguide chute permitting the tipping table to return to normal posiing jaws f pivoted at g and it respectively.

These jaws are shaped to the contour of the bottle but are of somewhat less internal diameter than the small diameter of the bottle. Consequently the speed of the falling bottle is checked, since it must spread the jaws apart against the action of their adjustable counterweights Y: and Z. Passing through the checking jaws, the bottleV is deposited in a suitable registering aperture in the usual rotary receiving table (not shown) and by it conveyed beneath the smoothing burners, with its neck up, instead of Vdown as hitherto. Y f

The apparatus is mounted on any suitable support by means of the brackets e, e, fast with the funnel-like body piece Z from which the checking jaws depend and above which the receiving table a. is supported by strap-like standards y and e.

Obviously the construction shown may -be variously'modied to attain the same result without departing from what I claim as my invention.

I claim as my invention l. In bottle handling apparatus, a receiving table adapted to receive a bottle from its mold, a pivoted table onto which the bottle. is discharge from the receiving table, said pivoted table tipping under the weight of the bottle and discharging the same in inverted position, together with a checking device through which the bottle passes after leaving the tipping table.

2. Inbottle handling apparatus, a receiv- Copies ofthis patent may 'be obtained for said pivoted table tipping under the weight l of the bottle and discharging the same in inverted position, together with a pair of kchecking jaws between which the bottle is frictionally engaged as it drops from the tipping table.

3. In bottle handling apparatus, a receiving table adapted to receive a bottle from its mold, a pivoted table onto which the bottle is discharged from the receiving table, said pivoted table tipping under the weight of the bottle and discharging the same in inverted position, together with a pair of pivoted counterweighted checking jaws between which the bottle is rictionally engaged as it drops from the tipping table.

4. In bottle handling apparatus, an inclined trough-like receiving table adapted to receive a bottle from its mold, a trough-like pivoted table forming practically a continnation of the lower portion of the receiving table and onto which the bottle passes from the latter, said pivoted table tipping under the weight of the bottle and discharging the latter in inverted position, together with a checking device through which the bottle passes from the tipping table, said checking device comprising a pair of jaws shaped to the contour of the bottle and yieldably held in frictional engagement therewith to check the speed of its fall.

In testimony that I claim the foregoing as my invention, I have signed my name in presence of subscribing witnesses.
